So Automattic had bought Gravatar a little while back, a service that is well known in the blogosphere for providing a way to easily display profile images, and now they have added the service to WordPress.com.
What’s that mean? When you have a WordPress.com account you can have an avatar by your comment, but now if someone isn’t logged in or registered but they have a Gravatar attached to their email account that will show up by their comments too. You may see a few new faces around. Gravatars help build a sense of community around your readers, and keep people coming back to the comments.
Since adding the service, Gravatar is now serving over 190 million image requests a day, a staggering number for me to wrap my brain around. Check out the full post at WordPress.com’s Blog.
